Preliminary Shielding Analysis for HCCB TBM Transport

         

摘要

A preliminary shielding analysis on the transport of the Chinese helium cooled ceramic breeder test blanket module(HCCB TBM) from France back to China after being irradiated in ITER is presented in this contribution.Emphasis was placed on irradiation safety during transport.The dose rate calculated by MCNP/4C for the conceptual package design satisfies the relevant dose limits from IAEA that the dose rate 3 m away from the surface of the package containing low specific activity III materials should be less than 10 mSv/h.The change with location and the time evolution of dose rates after shutdown have also been studied.This will be helpful for devising the detailed transport plan of HCCB TBM back to China in the near future.
